An interactive computer vision game that combines real-time face tracking, hand gesture recognition, and Arduino-controlled laser positioning for an immersive gaming experience. Navigate their face to ...

Lasers are some of the coolest devices around. We can use them to cut things, create laser light shows, and also as a rangefinder.[Ignas] wrote in to tell us about [Berryjam’s] AMAZING write-up on ...

Have you ever wanted to roll your own pinball machine? It’s one of those kinds of builds where it’s easy to go off the deep end. But if you’re just getting your feet wet and want to mess around with ...

The word LiDAR, the ‘Li’ meaning ‘light’ indicates a device for optoelectronic echolocation. Instead of radio frequencies, the Lidar transmits a pulsed laser beam, the echo of which allows the ...

Using a little Arduino hardware and programming maker and astronomer Görkem Bozkurt has designed and built his very own telescope mount which has been inspired by the GoTo telescope stands, and is ...

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer. The following is excerpted from the ...

A laser projector creates a light show that seems to be coming from dozens of laser beams. It only needs a single laser beam to create the effect because the beam is diffracted as it emerges from the ...

Jon Bumstead has created an awesome Arduino powered 13 note midi harp after receiving funding from the optics group Spectra at Washington University in Saint Louis. Watch the video below to learn more ...

This project is a Laser Morse Code Encoder and Decoder system designed to facilitate secure and efficient communication using light signals. Leveraging the simplicity and reliability of Morse code, ...
